I liked theone for Karin.
Scarlet by BRACE;D.
Or the inuyasha endings.

I love the RahXephon opening. It has great music and singing by Maaya Sakamoto, and the visuals are tantalizing to pique your interest!

my favorite anime openings/endings song are...

1midori no hibi ending song
2air gear opening song
3fate stay night opening+ending song

naruto(distance,hero's come back)
bleach(rolling star, life, after dark)

My favourite anime openings/endings are:

1. Chain (1st Opening of Air Gear), sung by Back-On. It's a really cool song. I always feel uplifted when I listen to this song.

2. Waltz (1st ending of Honey & Clover), sung by Suneohair. Very catchy and dramatic.

3. Life is Like a Boat (ending of Bleach), sung by Rie-Fu. Very touching and meaningful.

the old naruto opening-fighting dreamers and the naruto shippuuden ending-shooting star and the new one i just don't know the title

i like those songs from Ai Yori Aoshi, Fruit Basket, Cardcaptor Sakura and Inu Yasha..

ummm one mf my faves are the ff;

1. Fruits basket (opening and ending theme, For Fruit Masket and Small Prayer?)
2. Detective School Q (all of them)
